Mind you, Nvidia has better support of old DirectX than AMD GPUs, so your experience might differ.
on reddit and steam you can read a lot how the game doesn’t work right on anything Windows 8.x and newer.
However, when getting the settings right, this was not the case for me!
Note: I do have an optical DVD drive in my computer, so the DRM check for inserting in my Steam release, do not appear for me.
So you have to change 3 Settings in the Advanced Graphic options inside the game:
- Default is “Primary Graphic Device” –> Select your actual GPU
- disable “Incremental Rendering”
- disable “Animation Interpolation”
Bonus: You can apply a hi-res pack, currently, you just have to dig through the thread to find the right page, here the permalink to all the still valid downloads: http://forums.sierrahelp.com/viewtopic.php?p=97737#p97737
